Cook the pasta in a large pot of salted boiling water according the package directions; drain and set aside.

In a large pan, cook and chop the sausage over medium heat (add the minced garlic to the pan when the sausage is close to being done).

Use a paper towel to blot out the excess grease from the pan.

Turn the heat to low and stir in the butter and heavy whipping cream. Simmer for 3-4 minutes or until the butter is thoroughly melted.

Stir in the spinach and cook for an additional 3 minutes or until the spinach starts to wilt.

Add the parmesan to the pan and stir until it's well incorporated. Stir in the cooked pasta and enjoy immediately.
